Subject: [PATCH v2] f2fs: fix to check warm_data_age_threshold
Date: Tue, 17 Jan 2023 21:24:42 +0800	[thread overview]
Message-ID: <20230117132442.77645-1-frank.li@vivo.com> (raw)

hot_data_age_threshold is a non-zero positive number, and
condition 2 includes condition 1, so there is no need to
additionally judge whether t is 0. And let's remove it.
